ABSTRACT
Arsenic exposure is associated with the induction of hepatotoxicity. Current study was aimed to investigate the hepato-protective ability of polyphenolic components of Tamarix aphylla (TA) ethanolic extract against sodium arsenite (SA)-induced liver injury of rats. Significantly higher quantities of phenolic (318.7±2.5 mgg-1GAE) and flavonoid (250.69 ±3.3 mgg-1QE) contents were present. Inhibitory concentration (IC50) exhibited an excellent potential for antioxidant (IC50= 25.99 µg/mL) assay. High performance liquid chromatography (HPLC) confirmed the existence of myercetin (10.40ppm), sinapic acid (2.131ppm), kaempferol (0.486ppm), caffeic acid (5.094 ppm). Forty-two rats were divided into 7 groups. Group 1 received normal saline (2 mL/kg/day, orally for 21 days), Group 2 received SA (10mg/kg/day for 21 days), and Group 3 received SA alone for 7 days (10mg/kg) and continues with silymarine for 21 days (25mg/kg orally). Group 4, 5, 6 received SA alone for 7 days and continue with TA extract up to 21 days (125mg/kg, 250mg/kg, and 500mg/kg orally) respectively, and Group 7 received TA extract (500mg/kg) for 21 days. SA was administered to all treated groups for 21 days. Treatment with polyphenolic ethanolic extract of TA restored the hepatic indices and oxidative markers in a dose-dependent manner. The upregulation in tumor necrosis factor-α, interleukin-6, and cyclooxygenase-2 upon SA treatment suggesting inflammation was normalized by the treatment of rats. Above mentioned biochemical findings were supported well with histopathological screening. Present findings suggest that TA polyphenolic ethanolic extract could mitigate the oxidative stress and inflammation induced by SA in liver tissue.
